A tank, in the shape of a parallelepiped, has bulkheads | ENEM 2024 Yellow Test Question 153
7A tank, in the shape of a rectangular parallelepiped, has two vertical bulkheads inside, fixed to its base and to two opposite walls, perpendicular to them. These bulkheads, of negligible thickness, are installed in such a way as to divide the base of the tank into three congruent rectangles, with their heights equal to half and a quarter of the height of the tank.
The tank is supplied by an inlet located in the roof, through a pipe that discharges water at a constant flow rate, and it takes 12 hours to finish filling it.
Which graph describes, at each instant, the greatest height of the water column, among those that are formed throughout the filling of the tank?
